Queen Victoria gives the Queen Victoria London Stories, in which the twins stop a new Templar faction's bombing campaign. She also hosts the Buckingham Palace ball at the end of the main story and appears in The Dreadful Crimes and The Last Maharaja.
Mary Anne Disraeli introduces Evie to the Queen, who knows Evie was behind the theft of Gladstone's carriage. Rather than have her arrested she tells Evie to enjoy herself and try the cake.
Victoria asks the twins to stop Templars trying to regain power through terror: a dynamite boat, a train packed with explosives, an escaped leader and a plot to bomb Parliament. She hopes they will keep serving the Empire; they decline, Evie suggesting she drop her imperial ambitions, and the Queen accepts this and rewards them.
In Murder at the Palace she calls the twins in when a royal guard is found dead in her study, worried the Scepter with the Dove in her safe is the real target. In The Great Jewel Heist she hosts a gala at the Tower of London where the Templars try to frame Duleep Singh.
The day after the ball, told by Abberline that the twins and Henry Green stopped Starrick's plot on her life, she knights all three into the Order of the Sacred Garter, and reminds Evie she kept some cake for her.
A Night to RememberA Night to Remember is the final main memory: the twins enter the Queen's ball at Buckingham Palace, Evie retrieves the vault plans from the White Drawing Room while Jacob rescues captive Royal Guards on the roofs, and both face Crawford Starrick in the vault below.Benjamin Disraeli

He runs a curiosity shop in Whitechapel that doubles as the Brotherhood's bureau, introduces Jacob and Evie to their key allies and works alongside Evie on the search for the Shroud of Eden. His birth name is Jayadeep Mir.
Duleep Singh
Duleep Singh, the last Maharaja of the Sikh Empire, is Henry Green's great-uncle. He helps Evie find the Buckingham Palace plans in Family Politics, and is the central figure of The Last Maharaja missions, where the twins help him fight the British India Company.
